To allow remote user access to protected resources behind an SSL VPN gateway, you must configure these resources on the gateway. Remote users can access only the resources authorized to them after they establish an SSL-encrypted connection to the gateway and pass the identity authentication.

As shown in Figure 1, SSL VPN operates as follows:

1. The remote user establishes an HTTPS connection to the SSL VPN gateway.

In this process, the remote user and the SSL VPN gateway perform SSL certificate authentication.

2. The remote user enters the username and password.

3. The SSL VPN gateway authenticates the credentials that the user entered, and authorizes the user to access a range of resources.

4. The user selects a resource to access.

An access request for that resource is sent to the SSL VPN gateway through the SSL connection.

5. The SSL VPN gateway resolves the request and forwards the request to the corresponding internal server.

6. The SSL VPN gateway forwards the server's reply to the user through the SSL connection.

SSL VPN networking modes

Gateway mode

In gateway mode, the SSL VPN gateway acts as a gateway that connects remote users and the internal servers network, as shown in Figure 2. Because the SSL VPN gateway is deployed in line, it can provide full protection to the internal network but it affects data transmission performance.

Figure 2 Gateway mode

‌

Single-arm mode

In single-arm mode, the SSL VPN gateway is attached to the network gateway, as shown in Figure 3.

The gateway forwards user-to-server traffic to the SSL VPN gateway. The SSL VPN gateway processes the traffic and sends the processed traffic back to the gateway. The gateway forwards the traffic to the internal servers. The SSL VPN gateway is not a performance bottleneck in the network because it is not deployed on the key path. However, the SSL VPN gateway cannot provide full protection to the internal network.

Figure 3 Single-arm mode

‌

SSL VPN access modes

IP access implements secured IP communication between remote users and internal servers.

To access an internal server in IP access mode, a user must install dedicated IP access client software. The client software will install a virtual network interface card (VNIC) on the SSL VPN client.

To implement IP access, you must configure the following on the SSL VPN gateway:

· An SSL VPN AC interface.

· Routes to accessible IP resources. The routes will be issued to SSL VPN clients to instruct packet forwarding.

Figure 4 uses a ping operation to illustrate the IP access process. The administrator must first configure a route to the ping destination (server 10.1.1.2/24) on the SSL VPN gateway.

The access process is as follows:

1. The user installs the IP access client software and launches the client software to log in to the SSL VPN gateway.

2. The SSL VPN gateway performs the following operations:

a. Authenticates and authorizes the user.

b. Allocates an IP address to the VNIC of the user.

c. Issues the authorized IP access resources to the client.

In this example, a route to server 10.1.1.2/24 is issued.

3. The client specifies the allocated IP address as the VNIC's address and adds the route to the local routing table, using the VNIC as output interface.

4. The user pings the server address.

The ping request matches the route. Matching packets will be encapsulated by SSL.

5. The client uses SSL to encapsulate the ping request packet, and then sends the packet to the SSL VPN AC interface through the VNIC.

6. The SSL VPN gateway de-encapsulates the SSL packet into the IP packet and forwards the IP packet to the corresponding internal server.

7. The internal server sends a reply to the SSL VPN gateway.

8. The SSL VPN gateway uses SSL to encapsulate the reply packet and then sends the packet to the client through the SSL VPN AC interface.

Figure 4 Network diagram for IP access

‌

SSL VPN user authentication

To access resources through an SSL VPN gateway, a user must first pass identity authentication to log in to the SSL VPN gateway. User authentication methods include only username/password authentication and verification code authentication. If two authentication methods are enabled, a user must pass these two authentication methods before access to internal resources. For more information about users, see AAA configuration in User Access and Authentication Configuration Guide.

The username/password authentication process is as follows:

1. The SSL VPN user enters the login username and password on the SSL VPN login page. The username and password are sent to the SSL VPN gateway.

2. The SSL VPN gateway sends the received username and password to AAA for authentication, authorization, and accounting, or to a custom authentication server for authentication and authorization.

Configuring outbound dynamic NAT for SSL VPN IP access

About this task

When the device installs with multiple security modules, you must configure outbound dynamic NAT on the interface connected to the internal server to translate source IP addresses to ensure that the forward and return packets of a data flow are forwarded to the same security module.

If no source address translation is performed, the forward and return packets of a data flow might be redirected to different security modules because of the following:

· When the SSL VPN gateway receives a user packet that accesses the internal server, it uses the source IP address of the packet (the IP address of the physical NIC of the user host) to select a security module through hash computation.

· When the SSL VPN gateway receives the return packet, it uses the destination IP address of the return packet (the IP address of the virtual NIC of the user host) to select a security module through hash computation.

· The security modules selected by the two hash computations might be different.

In this case, configure NAT to translate the source IP address of the packets between the SSL VPN gateway and the internal server and generate OpenFlow entries to ensure the forward and return packets of a data flow are redirected to the same security module.

For more information about NAT, see Network Connectivity Configuration Guide.

Restrictions and guidelines

Configure outbound dynamic NAT on the interface connected to the internal server to translate source IP addresses.

Make sure the IP addresses in the NAT address group are in the same subnet as the interface where NAT is configured.

Make sure you configure NAT source address translation for the IP address of the IP client (virtual NIC).
